13. Estudo da incorporação de altos teores de argila calcinada no concreto compactado com rolo / Study of the incorporation of high amounts of calcined clay in roller compacted concrete
The rolled compacted concrete (RCC) is a still relatively new technique, but with growing volume of use, a fact generated by its technical and economical advantages, requiring more studies in order to use with greater efficiency, safety and economy. This work deals with the RCC with high levels of replacement and addition of part of the Portland cement by ca

14. Sistema de irrigação por capilaridade na produção de porta-enxertos de mudas citricas na fase de sementeira / Irrigation system by capillary action in the citrus rootstocks production in seedings stage
The water and nutrition management in the production of citrus rootstocks in the seedling phase performed by sprinkler systems, manually operated, presents the environmental outcome of water or residual solution disposal from the fertigation. The generated wastewater is generally discarded directly in the soil with the risk to reach the groundwater and conta

15. Análise de propriedades térmicas e mecânicas de compósitos de argamassa e resíduo de borracha
Although already to exist alternative technique and economically viable for destination of used tires, quantitative data on properties of constructive elements that use the rubber waste as aggregate still are restricted. In the present work, the waste proceeding from industry of retreading as material for manufacture of composite destined to the production o

16. Atributos mecÃnicos e salpicamento de partÃculas em amostras de latossolo vermelho-amarelo sob efeito de vinhaÃa / Mechanical attributes and splash of particles of samples of red-yellow latosol (Oxisol) under effect of vinasse
With the increased production of ethanol and cachaÃa in Brazil, also increases the production of vinasse, main residue of the industrialization of sugarcane. One way of its utilization is its disposal in soil as liquid fertilizer. The vinasse can change the physical attributes of soil and its compressive behavior and the resistance of soil aggregates to spl

17. Effect of Ti and Nb Additions on the Formation of Craters for IF Steel Galvanneal Coatings
Interstitial Free steels feature alloying elements present in an ultra low C matrix that account for C stabilization and consequently a high number of C free interstitials in a ferrite matrix that give these steels the ideal texture, low yield point, favorable plastic strain ratios, high elongation and n-value necessary for an ideal performance on forming pr

18. Hemorragia alveolar fatal: estudo histológico detalhado de necropsias / Fatal alveolar hemorrhage: detailed histological analysis of necropsies
Alveolar haemorrhage is a syndrome presented by many diseases each one with its particular physiopathologic mechanism resulting in pulmonary bleeding. The detailed histological analysis of these patients can help understanding this syndrome. In this study we reviewed and described histological findings of lung slides and medical records from patients whose c

19. FLOW OF EMULSIONS IN POROUS MEDIA: EXPERIMENTS AND CAPILLARY NETWORK MODEL / ESCOAMENTO DE EMULSÕES EM MEIOS POROSOS: EXPERIMENTOS E MODELO DE REDE DE CAPILARES
Objective: Transport of emulsions in porous media is relevant to several subsurface applications. Many enhanced oil recovery processes involve emulsion formation and their flow in some form. Modeling the flow of emulsion in porous media is extremely challenging. The available descriptions based on effective viscosity are not valid when the drop size is of th

20. Programa Nossocrédito : uma análise do processo de formulação e implementação da política de microcrédito do Estado do Espírito Santo
This study examines the policy of microcredit in the state of Espírito Santo, called NOSSOCRÉDITO, from the processes of formulation and implementation of the Program, set up by the States government in August 2003, to its recent achievements, including the period between August 2003 and April 2008. It investigates the specifics of the program given the co

21. Time course of training-induced microcirculatory changes and of vegf expression in skeletal muscles of spontaneously hypertensive female rats
Exercise-induced vessel changes modulate arterial pressure (AP) in male spontaneously hypertensive rats (SHR). Vascular endothelial growth factor (VEGF) is important for angiogenesis of skeletal muscle. The present study evaluated the time course of VEGF and angiogenesis after short- and long-term exercise training of female SHR and Wistar Kyoto (WKY) rats,

22. FROM SPECTACULARIZATION TO POLITICAL AGENDA: A POLITICAL APPROACH OF LGBT MOVEMENT / DA ESPETACULARIZAÇÃO À AGENDA POLÍTICA: UMA LEITURA POLÍTICA DO MOVIMENTO LGBT
This research deals with the issue of political representation system capillarity, particularly of political parties in a context in which it is possible to observe an explosion of political demands from multiple new subjectivities. In this sense, the GLBT Movement will be presented as a case study, in two dimensions of their struggle. On one hand, a dimensi

23. Aproveitamento de resíduos minerais na formulação de argamassas para a construção civil
Current environmental concerns include the excessive consumption and inefficient use of non-renewable natural resources. The construction industry is considered one of the largest consumers of natural raw materials, significantly contributing to the environmental degradation of the planet. The use of calcareous quarry (RPPC) and porcelain tile polishing resi

24. Avaliação da retração autógena em concretos de alto desempenho com diferentes adições
High performance concrete is commonly useful by its performance, strength, durability, workability and others. Autogenous shrinkage can be considering one of the reasons of cracks on high performance concretes at early ages. The concrete shrinkage can be influenced by different reasons: piece measurements, water content of mashing, dosage of cement, inert na
